| Summary: | 'Solum' barley was planted in four large acreage demonstration studies in Maricopa County from 1990 -92. In two of the four demonstrations, a single fruit set cotton production strategy was implemented resulting in a double crop/rotation in the same year. Barley yields were 4672, 4460, 4305, and 4721 pounds per acre respectively. These yields were accomplished with 13 -20 acre inches per acre of water both from irrigation and rainfall sources. All demonstrations resulted in a positive net return of from 150 to 200 dollars per acre. In addition, physical soil characteristics such as tilth, water holding capacity, and intake rate were significantly improved. A cotton yield of roughly two bales per acre was measured in one location with the 1992 yield to yet be determined.
